Blog & User Creator

I'm guessing this can be resoved in the main functions.php file, but I'm attempting to add blogs for existing student users. The problem is we've used their student ID numbers as their usernames. I get an error stating that blog/user names must have letters too when using the blog/user creator plugin. Obviously, I was able to create user accounts (without blogs) using just student id numbers. Any thoughts on what I need to change to enable blogs to be associated with these users?

This is still the default behavior of WordPress. I found a recent mu-plugin that allows less than 4 character usernames so you don't have to hack the core. Maybe it could be adjusted to allow strictly numerical usernames as well?

Interesting read although it refers to mu-plugin and i'm using wordpress 3.01 with multisite. I followed the instructions provided by the creator of the plugin and it doesn't show up in the plugins screen.

mu-plugins is still a valid directory for WordPress Multi-site (and necessary for many plugins). It stands for "Must Use" which means WordPress must use it and thus, doesn't require any activation. You won't see any changes other than what the plugin is designed to do, which in this case is modify the allowed signups.

Again, you'd still have to modify the code to get it to do what you're looking for, but this gets you in the right ballpark. ;D
